How do you undo a hidden distracting item?

I have Safari 18 on macOS 14.7 and on one site I've hidden a "distracting item" but found that it prevents the website from scrolling when it appears and is subsequently "hidden" by safari. I've sent feedback to Apple about this already.

What I can't find out how to do is how does one remove (not disable for a limited time by "Show Hidden Items") the hidden items I've selected. I've selected two distracting items for this website and just want to remove/undo/reset the hidden item list for this website so instead of 2 items, it's zero. I can't discover how to accomplish this task on my own; the gulf of execution here is too high for me.

Is there even a way to reset the hidden item list for a website? Thanks!
